Reducing chimney tee DN 110/130 for boilers with an open combustion chamber SJBT90R110130

Reducing Chimney Tee DN 110/130

Manufactured from acid-resistant sheet metal — a material resistant to corrosion caused by flue gases, ensuring durability in the operating conditions of solid-fuel boilers with an open combustion chamber. This is not ordinary stainless steel: the special composition of the sheet metal is tailored to the aggressive internal environment of chimneys, where condensation and acids form as a result of solid fuel combustion.

The product name includes dimensions DN 110/130 — indicating that it is a reducing element, connecting a larger-diameter pipe (DN 130) to a smaller one (DN 110). This is confirmed by the catalog number SJBT90R110130, where "R" denotes reduction.

The 90° angle allows for a change in the direction of the flue gas duct without the need for two separate components. Installation is carried out in single-wall systems — as stated by the online source — and only for solid-fuel boilers. It is not suitable for gas or oil boilers, even if their flue gases are aggressive — the product has not been designed or tested for these types of appliances.
